What part of my description implied "wandering around"? The whole point was they were doing the best they could to travel safely and it failed partly because of outside events.
Honestly, this comes across as a pretty disingenuous response to the scenario I presented.
No. It required one decision, prompted by an event they had no control over, and a single failed roll. People are going to travel; acting like that was an odd decision and unsafe is kind of off here.
Again, the thought they were taking it seriously; they had a path and a map. In that situation when a big storm breaks out you have a bad set of choices, but it isn't something you can always account for.
Remember, my comment wasn't about fail forward per se; it was that single points of failure can be a problem well outside story-focused games. Fail forward is just one tool to address this, but its absolutely a thing people need to think about, one way or another.
Your scenario appears, to me, to be:
A group of seasoned, skilled outdoor survivalists are travelling in the wilderness. They lose their map and, because the map is lost, are now out of options and their survival is going to come down to dumb luck or desperate hail marys. Can they not judge directions? Does no one have any idea where they've come from? Are there no landmarks anywhere? Are they incapable of foraging or hunting for food? How have they suddenly gone from "fine" to "all is lost, there's no way out"?
Outside events might make things harder, but a single event isn't typically going to make things impossible. If it's one event after another, but the group keeps pressing forward, again and again, refusing to turn back, until eventually it's too late, then that's not outside events, it's is either foolishness
or it's an assumption by the players that the GM is going to bail them out or not let things get that bad. If it's the latter, and those assumptions are wrong, that's a communication problem, not a system problem.
If it's some extreme example, where they're crossing an icy tundra known for week long blizzards that kill even the most experienced native experts, well, either that description of the region means something, and you are genuinely risking death if you choose to set out, or it doesn't, in which case sure, you can use any one of a number of methods to make sure it doesn't happen. If it's not really meant to be deadly to the PCs, then the easy fixes are to either not put them in the deadly blizzard, or make sure it ends before they're out of meaningful options. But either way, I don't really see how you "accidentally" end in a position where no one has any option. And again, if it is just a mistake by the GM (oh, this weather chart was a bad idea, I didn't intend for this outcome that no one will enjoy), then
just say so. No need to be coy about it.
But I genuinely struggle to see how a "no way out, except based on this single binary roll" situation can just sneak up on everyone with no meaningful opportunity to prevent it by any of the participants -- it it happens, it's something everyone has embraced and accepted as an outcome they're willing to live with.
Edit: And, if you still think I'm being disingenuous, there must be something one of us is saying that the other is just not grasping, because I'm definitely not trying to be intentionally obtuse here, or to misrepresent your scenario.
